Fleeece works great and you don't need batting - buy the kind of fleece that says it will not pill as excess use may make them look "pilled" after a while if you use them a lot. I have one and have used fleece on baby quilts - and it wears really well, and is so cuddly warm. Love them; plan to use fleece or flannel on the backs of all my quilts especially lap quilts and throws from now on. I love the flannel on teh back of the bed sized quilts too - seems warmer - or cozier at least than plain cotton or muslin.
